摘要
随着高速铁路隧道开通运营里程的增加,部分隧道由于受外力、地下水环境变化、施工工艺等因素影响,产生结构劣化,影响了运营安全。隧道病害整治措施的选择具有局限性,应尽量避免大拆大改,利用原结构进行加固、补强。本文通过对铁路运营隧道的冷缝病害分析,对套衬设计方案及施工技术进行研究,总结能够用于类似工程的相关措施,以有效降低运营条件下的施工风险,确保后期运营安全。
With the increasing length of high-speed railway tunnels,some tunnels suffer structural deterioration due to factors such as external forces,changes in groundwater environment,and construction technology,which affects the operation safety.There are limitations in the selection of treatment measures for tunnel defects.It is necessary to avoid large-scale demolition and reconstruction and use the original structure for reinforcement.This paper analyze the cold joints in tunnels in service of operating railway,studies the design scheme and construction technology of lining,and summarizes the relevant measures that can be taken in similar projects,so as to effectively reduce the construction risks in operation and ensure the safety of later operation.
